Professor Sir John Beddington, the UK’s Government Chief Scientific Adviser, gave a talk in Tokyo last month within the context of the Fukushima Nuclear Incident saga. The talk is long (and I skipped the Q&A part), but quite informative. Two take-home message I got from this are: (i) The UK government has been running numerical models using worst-case scenarios for the purpose of evaluating risks for the UK Citizens living in Japan; and (ii) they have concluded that there is no need for advising the UK citizens to evacuate the greater Tokyo region at this point.
I do think about the risks and benefits of taking my kids to Tokyo next month. I had already decided the benefits far outweigh the risks. But this talk made me feel better. I mean, it is nice to have someone else quantifying the risks for me.
